151; during assembling, each elastic rope 15 winds across the frame
unit 11, and the two ends on each elastic rope 15 are hung on the
corresponding fixing component 14; since the fixing components 14
are used for improving the structural strength, the first existing
trampoline has the disadvantages that the fixing components 14 are
relatively large and thick, and protrude out of the surface of the
bouncing cloth 12, and users can be injured easily; the joints 151
of the elastic ropes 15 are generally provided with sharp corners
which cannot be hidden, and consequentially, users can also be
injured easily.
Please see FIG. 3, a second existing trampoline 1 is different from
the first existing trampoline (shown in FIGS. 1-2) in that each
fixing component 14 is provided with two raised columns 141, and
the two ends of each elastic rope 15 are knotted into two rings 152
to form two joints 151 for fixing; during mounting, the elastic
ropes 15 wind across the frame unit 11 to be hung on one side of
the fixing components 14 first, then the two rings 152 of each
elastic rope 15 are hung on the corresponding raised columns 141
respectively, and thus fixing is completed; according to the second
existing trampoline 1, the two ends of each elastic rope 15 need to
be knotted into the rings 152 first, early-stage work is
troublesome, and due to the existence of the raised columns 141,
the second existing trampoline has the same disadvantage as the
first existing trampoline that users can be injured easily.
Please see FIG. 4, a third existing trampoline 1 is different from
the second existing trampoline (shown in FIG. 3) in that each
fixing component 14 is composed of two grooves 142 instead of the
raised columns 141 (shown in FIG. 3), and the two ends of each
elastic rope 15 are knotted into two rings 152 to form two joints
151 for fixing; during mounting, the elastic ropes 15 are embedded
into the grooves 142 and clamped and limited through the joints
151, and similarly, the third existing trampoline has the same
disadvantage with the second existing trampoline that users can be
injured easily.
Please see FIG. 5, a fourth existing trampoline 1 is different from
the third trampoline (shown in FIG. 4) in that the two ends of each
elastic rope 15 are knotted into ring knots 153; during mounting,
the elastic ropes 15 are embedded into the grooves 142 and clamped
and limited through the ring knots 153, and similarly, the third
existing trampoline has the same disadvantage with the third
existing trampoline.
Please see FIG. 6, a fifth existing trampoline 1 is different from
the second existing trampoline (shown in FIG. 3) in that the number
of the elastic ropes 15 is less than the number of the fixing
components 14, each fixing component 14 is provided with at least
two raised columns 141, and after each elastic rope 15 is hooked
and wound on the corresponding raised columns 141 repeatedly and
each elastic rope 15 is wound across the frame unit 11, the two
rings 152 of each elastic rope 15 are hung on the corresponding
raised columns 141, and thus fixing is completed; by adoption of
the mounting method, when the trampoline is in use, loosening and
falling occur easily, safety cannot be guaranteed in use, and the
fifth existing trampoline has the same disadvantage with the second
existing trampoline.

the through groove direction L from the end, away from the bouncing
cloth 41, of the body 51, a clamping and abutting section 55
extending towards the bouncing cloth 41 from the end, away from the
body 51, of the extension section 54, a clamping space 56 defined
by the body 51, the extension section 54 and the clamping and
abutting section 55 in cooperation, a through hole 57 penetrating
through the body 51 in the through groove direction L, and a
limiting component 58 penetrating through the through hole 57 to
clamp and limit the corresponding elastic rope ring 6 in the
clamping space 56 (as is shown in FIG. 11), and each connection
belt 42 penetrates through the corresponding through groove 52 and
is tied on the corresponding connection body 53 in a sleeving
mode.
The connection body 53 of each hanging seat unit 5 is provided with
a first end part 531 and a second end part 532 which are formed at
the two ends respectively, and the first end part 531 and the
second end part 532 both stretch out of the body 51 and used for
stopping and limiting the corresponding elastic rope ring 6.
The side, away from the bouncing unit 4, of the extension section
54 of each hanging seat unit 5 is provided with a concave arc
surface 541, and the curvature center of the concave arc surface
541 is away from the bouncing unit 4.
Each elastic rope ring 6 is in a closed ring shape and connects the
bouncing unit 4 with the corresponding hanging seat unit 5 around

shown in FIG. 11). Each elastic rope ring 6 is in a closed ring
shape, during manufacturing, the two tail ends of each elastic rope
are connected, so that a protruding joint 61 is formed at the
junction of each elastic rope ring 6.
When the bouncing unit 4 is about to be mounted on the frame 2, one
end of one elastic rope ring 6 is tied on the connection belt 42
located between one hanging seat unit 5 and the bouncing cloth 41
in a sleeving mode from bottom to top firstly, and then the elastic
rope ring 6 is stretched outwards, winds across the frame 2 from
top to bottom and draws close to the space below the hanging seat
unit 5, wherein during stretching, it should be noticed that the
end, close to the bouncing cloth 41, of the elastic rope ring 6 is
located between the first end part 531 and the second end part 532,
then the end, away from the bouncing cloth 41, of the elastic rope
ring 6 is arranged in the corresponding clamping space 56 in a
sleeved mode and tied on the corresponding extension section 54 and
the corresponding clamping and abutting section 55 in a sleeving
mode, finally one limiting component 58 is made to penetrate
through the corresponding through hole 57, the end of the elastic
rope ring 6 away from the bouncing cloth 41 is limited and clamped
in the corresponding clamping space 56 (shown in FIG. 11), and thus
the elastic rope ring 6 is mounted; then the above steps are
repeated until all the elastic rope rings 6 are mounted, and thus
mounting is completed.
What should be mentioned is that the outward-stretching motion is
conducted after the joint 61 formed on each elastic rope ring 6 is
arranged below the bouncing cloth 41 during mounting (as is shown
in FIG. 10) so that the joints 61 can be hidden below the bouncing
cloth 41, and injuries to users are avoided when the trampoline is
used.
Please see FIG. 12, a second embodiment of the utility model is
different from the first embodiment in that each hanging seat unit
5 further comprises a stopper set 59 which is formed on the
corresponding connection body 53 and used for stopping and limiting
the corresponding elastic rope ring 6; each stopper set 59 is
composed of two raised columns 591 which extend in the through
groove direction L, wherein the raised columns 591 are adjacent to
the first end part 531 and the second end part 532 respectively,
and the extension direction of the raised columns 591 is opposite
to the extension direction of the extension section 54. During
mounting, the above mounting method is adopted, however, it should
be noticed that in the stretching process, the end, close to the
bouncing cloth 41, of each elastic rope ring 6 is located between
the corresponding raised columns 591, and thus the effect of
limiting and clamping the elastic rope rings 6 can also be
achieved.
Please see FIG. 13, a third embodiment of the utility model is
different from the second embodiment in that each stopper set 59 is
composed of two baffles 592 which extend outwards from the first
end part 531 and the second end part 532 respectively, similarly,
it also should be noticed that in the stretching process for
mounting, the end, adjacent to the bouncing cloth 41, of each
elastic rope ring 6 is located between the corresponding baffles
592, and thus the effect of limiting and clamping the elastic rope
rings 6 can also be achieved.
In conclusion, the trampoline with the hanging seat units that
allows elastic ropes to be mounted easily of the utility model has
the following advantages that:
Firstly, both ends of each elastic rope 15 mentioned in the prior
art are connected to the same fixing component 15, and each fixing
component 15 can be large in size and extremely thick; however,
each hanging seat unit 5 in the utility model is only connected
with one end of the corresponding elastic rope ring 6, and thus
each hanging seat unit 5 small in size and extremely thin and
cannot protrude out of the surface of the bouncing cloth 41 after
being mounted, and injuries to users are avoided.
Secondly, in the process of manufacturing the elastic rope rings 6,
only the two ends of each elastic rope need to be connected to form
one joint 61, and compared with the prior art, operation is easy
and convenient; during mounting, outward-stretching motion is
conducted after each joint 61 is arranged below the bouncing cloth
41, so that the joints 61 are hidden below the bouncing cloth 41,
attractiveness is guaranteed, and injuries to users are avoided
when the trampoline is used.
Thirdly, through the design of the first end part 531 and the
second end part 532 of each connection body 53 and the raised
columns 591 or the baffles 592 of each stopper set 59, the end,
adjacent to the bouncing cloth 41, of each elastic rope ring 6 can
be clamped and limited and be prevented from disengaging from the
corresponding connection body 53, and thus the safety in the using
process is improved.
Fourthly, through the limiting components 58 which penetrate
through the corresponding through holes 57 to clamp and limit the
corresponding elastic rope rings 6 in the clamping spaces 56, the
end, away from the bouncing cloth 41, of each elastic rope ring 6
can be clamped and limited and be prevented from disengaging from
the clamping space 56, so that the safety in the using process is
improved, and the purposes of the utility model can be realized
truly.
In conclusion, the foregoing descriptions are only embodiments of
the utility model, however, the scope of the utility mode is not
limited to the foregoing description, and all simple equivalent
changes and modifications made according to the scope of the claims
and the content of the description of the utility model are still
within the scope of the utility model.
